Annotation for marking a method for handling
a specific event.
The GenericPortlet tries to dispatch to methods annotated
with the tag @ProcessEvent for any received event.
Event QName.
Must be in the format:
"{" + Namespace URI + "}" + local part.
If the Namespace URI equals(XMLConstants.NULL_NS_URI),
only the local part is used
(like the javax.xml.namespace.QName.toString() method).
Local part of the event name.
The namespace for the events is either taken from the default-event-namespace element
in the portlet deployment descriptor, or if this element is not provided
the XML default namespace XMLConstants.NULL_NS_URI is used.
